[Xen-devel] [PATCH][XM-TEST] Test that tries to create a 16MB domain

[Dan Smith <danms@xxxxxxxxxx>]

This patch adds a test that tries to create a domain with only 16MB of
RAM.  It verifies that the domain is created and that the console
works.

Right now this test fails for me: the domain just dies immediately
with no indication of why, or with any useful console data.  Should we
put a sanity check on xm's create and mem-set commands that prevent
the user from doing something we know won't work?  Perhaps we can add
a --force flag to allow overrides.

Thoughts?
